7.7 Adding Channels and an SWI to the Configuration File

The A2DscaleD2A function is called by an SWI object and uses two HST

objects. You create these objects in this section. (The hostio.cdb file in the

c:\ti\c6000\tutorial\hostio2\ folder already contains these objects.)

The A2DscaleD2A function also references two PIP objects, but these

objects are created internally when you create the HST objects. The

HST_getpipe function gets the address of the internal PIP object that

corresponds to each HST object.

1) In the Project View, double-click on the HOSTIO.CDB file to open it.

2) Right-click on the HST manager and choose Insert HST.

Notice that there are HST objects called RTA_fromHost and RTA_toHost.

These objects are used internally to update the DSP/BIOS controls.

3) Rename the new HST0 object to input_HST.

4) Right-click on the input_HST object and choose Properties from the

pop-up menu. Set the following properties for this object and click OK.
